Paid.Paid by the millisecond on a line, or one block per call without one. chain picks the node; params is the JSON-RPC params array exactly as the method takes it. Any method the node serves, answered in one piece: aA call the line cannot cover is cut when the balance empties, with nothing back, and theits time is spent. There is no per-call limit — what you put on the line is what a call mayruns spend;out; page a wide eth_getLogs yourself. To check the node free, sample_rpc. For volume, POST /rpc/{chain}: the same node, price and paymentprice with no MCP framing, so each call holds the meter for less; aframing; streamsubscriptions isare the websocket there.
